/**
 * 核心原理
 * 1) @EnableRedisHttpSession 导入配置RedisHttpSessionConfiguration
 *  1.给容器中添加了一个组件
 *      SessionRepository=>RedisOperationSessionRepository:redis操作session .session的增删改查的封装类
 *  2.SessionRepositoryFilter=>Filter:session存储过滤器:每个请求都必须经过Filter
 *      1.创建的时候,就自动从容器中提取到了SessionRepository
 *      2.原始的request,response都被包装了SessionRepositoryRequestWrapper,SessionRepositoryResponseWrapper
 *      3.以后获取session.request.getSession
 *      4.wrapperRequest.getSession() ==>SessionRepository中获取到的
 *  装饰者模式:
 *
 *  自动延期:redis中的数据也是又过期时间的
